The scientific community agrees that a vaccine is essential to resuming anything resembling normal life. But on a societal level, vaccines only work if they’re widely adopted. Abram Wagner, research assistant professor of Epidemiology, explains.
Long before we could sequence a virus’s genome in a matter of weeks, we used public health tactics like contact tracing to sort out the movement of a disease in a population. Contact tracing is one of the “traditional” tools of epidemiologists. Today, we have more public health surveillance tools at our disposal, and we’ll need both the old and the new to bring COVID-19 under control.
We’re all wondering when we can return to work, see friends and family, and get back to some sense of normal. Meanwhile, we might notice that a planned temporary hospital wasn’t built or that some data seems to show a reduction in the spread of coronavirus. What do we do with emerging shades of gray in a situation that seemed so black and white not too long ago?
